Eurokraft retrotrams where designed and produced for the 130th anniversary of tram in Tallinn. In trams are wooden seats (made of oak) for 33 passengers. Altogether there is place (seats&standing) for 170 passengers. Our retrotram is four-axle type tramcar and uses the boogies which were developed by the Czech firm ČKD Tatra for their tram model KT4.

A „retro tram“ stands for a renovated and reconstructed tramcar based on the frame and the body of the tram KT4 thus being similar to trams manufactured in 1940 – 1960 both in content and in form whereas it´s equipped with a modern control system and passenger information system.
Our most experienced engineers and technologists have worked at designing the retro tram while striving for it´s personality and technical functionality.
Retro tram is not only a means of transportation but also an important part of the architectural appearance of the city. The color scheme for the exterior is tailored to the cultural characteristics of the state, ensuring the perfect fusion of the tram with the urban environment. A special feature of this tram is a pantograph that has two main advantages: trams can develop the highest possible speed whereas the contact network is simple and cheap to maintain.
The main objective in the creation of the interior was to bring it as close as possible to the interior of the trams that were running in Tallinn in the 1940s and 1960s, while making the inhabitants´ commuting as comfortable as possible. The basic materials used in interior are wood and metal which best reflect the style of that time. To create an atmosphere of coziness, we used LED lighting with bright warm light, trying to keep the shape of lamps as close as possible to retro.
In the interior design, we paid special attention to the seats and their location which helped us to more accurately convey the interior design of the trams of 1940-1960.
Before the final acceptance of the tramcar a number of tests are carried out, such as brake tests and high voltage tests. The main purpose of brake tests is to check the braking performance of the tram when driving at different speeds. Based on the results, the requirements for traffic safety and permissible speeds are evaluated. The high voltage test enables us to ensure the availability of a sufficient isolation strength, which is impossible to determine by any other method.
All the tests are conducted exclusively under the supervision of highly qualified engineers, in accordance with the current technical documentation and safety regulations
